Don't quote me and I don't wanna start a UPS vs. FDX ground war but, it seems to me that ground's prices are always (or least the few times I've compared) lower. Plus, ground's transit times are coming way down. They're quoting 5 bus. days to go from CA to MA.

Is it true that ground took over the remaining shipping of Amazon frt. from UPS?
That seems like it would be a big blow.
And, DS, you gotta realize I work for eggpress so, I don't have any dog in the fight.

UPS could buy another company, make enough campaign contributions to enable the use of very questionable employment practices/status, which in turn allows them to pay the other opco a third of the wages, no benefits, have no vehicle maintenance ,keep the union out, and then slowly shift all the volume over.
We can call this company UPS el Grounde.....
